上下動を考慮した簡便な盛土の地震応答解析手法の提案 A Proposal on the Simple and Easy Method of Seismic Response Calculation of Embankments Considering Vertical Seismic Motion 秦, 吉弥 Hata, Yoshiya 秦 Hata 吉弥 Yoshiya 土田, 孝 Tsuchida, Takashi 土田 Tsuchida 孝 Takashi 加納, 誠二 Kano, Seiji 加納 Kano 誠二 Seiji 山下, 典彦 Yamashita, Norihiko 山下 Yamashita 典彦 Norihiko open access Embankment, horizontal and vertical seismic response, modified Newmark method 520 Since the UD direction ground motions of the Hyogoken-nambu and Niigataken-chuetsu earthquakes were very large, it suffered the seismic damage that earth structures was very enormous. However, the effects which vertical seismic motion exerts on the destruction of embankment aren't taken sufficiently into account in the seismic design of the earth structures, So, in this study, the simple and easy calculation method of seismic response calculation that the vibration characteristics in the horizontal and vertical direction of embankments were taken into consideration at the same time is proposed. Then, the modified Newmark method that response characteristics in both directions of embankments were taken into consideration is proposed. 広島大学大学院工学研究科 2006-12 jpn departmental bulletin paper VoR https://hiroshima.repo.nii.ac.jp/records/2032430 1347-7218 AA11700032 広島大学大学院工学研究科研究報告 Bulletin of the Graduate School of Engineering, Hiroshima University 55 1 27 27 34 https://hiroshima.repo.nii.ac.jp/record/2032430/files/AA11700032_55_1_27_2006.pdf 791.5 KB
